Y UNITED STATES PATENT OFFICE Tron or DELAWARE 1 V raysra'mon'Application meanareh s,

Th present invention relates in general to inultiwcoin paystationdevices designed for usein conjunction with and as a partof thesubstation equipment of a subscribersline in an automatic telephonesystem. More specifically, the invention is concerned with the provisionof a unitary multhcom paystation device in which the deposit of acoinneed not he made until the subscriber called responds, or, in the caseofa toll connection,

untilthetoH operator has obtained a desired x party and requested thecalling subscriber to necessary to pay for where many toll calls areinitiated, it is quite advantageous to provide means wherehy coins canalso he collected to pay for such connections. Thisneed has heretoforebeen met, after a fashiolnhy increasing thesize of the base upon whichthe pa-ystation shown in theMadsen patentwas formerly mounted,

It a toll call is set up. theoperator. instructs the subscriber. to deposit the required coinorcoinsin the multi-eoin device and supervises the deposit of the coins bylistening to the coin actuated signals asis done in supervising thedeposit of coins in a pay station such as shown inthe previouslymentionedForsberg and Long patents.

Since in the present invention no coincollect orrefund operations are necessary, alla-pparatus of this character isomitted, but the downwardly projectingextem sion, of thearmature of thepolarized magnet, formerly used for these operations, is

used instead for controlling the operation of an additional set ofcontactsprings similar to those actuated bythe polarized magnetdisclosed in the Madsen patent.

The invention is disclosed in two sheets of "drawings, comprising Figs.1 to .5, inclusive. a: Fig. l is a front vew of the device, in elevation; Fig.2 diagrammaticallyillustrates the circuits andapparatus; Fig.3 is a frontview, in elevation of the electro-magnetic part of themechanism 'in normalposit'ion; Fig. 4; is

a rear View of Fig. 3 in elevation with cer tain parts omitted forsakeof clearness and with the various parts shown in operated position;while Fig. 5 is a View of a portion of Fig. has seen from the left. Italso shows a section of a portion of an associated coin chute. i

Referring now to Figs. 2-5, inclusive, a detailed description will begivenof the polarized magnet and its associated parts, after ing arm 12,shown in Figs. 2 and 3 and an arm 12 shown in Figs. 2, 4 and 5, to whichis secured an extension 11 pivotally support- I ing a spring actuatingarm 13.

The free end of arm 13 1s supported bya small bracket 18 secured to adoubl'earm lever 26, which is also pivotally secured to upwardlyextending portionsof the previously mentioned plate 23. The lever 26functions in substantially the same manner I as does the lever 113 ofthe Forsberg patent previously referred to. The arm 27 of the lever 26is moved into the position in which it is shown in Figs. 3 and 5 by thebushing on extension 12' of the armature plate 12. And although atension spring 32 tends to movethe arm 27 and close contact springs 29,upon movement of the armature 11 to its reverse position, the

movement of arm 27 is prevented by the coin trip lever 30. The depositof acoin in the coin chute, however, will cause the lever30 tomomentarily swingout of the path of movement of arm 31 and permit thetension spring 32 to rotate the lever 26 to cause its arm 27 .to closecontact springs 29.

The actuation of the-armature 11 to'its'alternate position causes thesprings 19 to be closed by armature extension 12; causes the arm 11 tomove the spring actuating arm 13 to the right, as viewed in Figs. 2 and3 and with it the tension of spring 33into the position in which it isshown in Fig. '4. The movement of the spring 33 away from the bushing onspring 16 permits the tension of spring 16 to become effective to bringthis spring and the associated springs 14 and 15 into contact witheach-other. When a deposited coin actuates lever 30 and. causes thelever 26 to be rotated in the manner previously mentioned, not only arethe contacts 29 closed, but also the free end of lever 13 is slightlyelevated by rotation of the bracket lever 26 sufficiently to causethebracket 18 to move the arm 13 clear of the top of spring 33. Spring 33,therefore, again becomes effective to overcome the tension of spring 16.

This results in the springs 14, 15 and 16 again being separated.

I If now the armature is restored to itsinitial position, as shown inFigs. 1, 2, 3 and 5,

the bushing on extension 12' of the armature plate 12 will rotate thelever 26 clockwise; the

arm 27 will again force the tension spring away from contact springs 29,permitting them to open the short circuit around winding 24; lever 18will be again lowered permitting arm 13 to again drop behind spring 33;and the arm 27 will be elevated sufficiently to permit coin actuated arm30 to restore, by gravity, to its normal position.

In view of the foregoing description and of the disclosures in thepatents hereinbefore referred to, it is believed that the invention canbe most readily made clear by describing its mode of operation in atypical installation. I v g Referring now to Fig.2, it will be assumedthat the subscriber at substation A desires to set up aconnection tosome other local subscriber .of the system. Upon the removal ofthereceiver 20.:at substation A, a circuit is closed, over which currentfrom the exchange battery (which is normally bridged across the-lineconductors 1 and 2, in series with the line relay associated with thecalling line) flows as follows from the-exchange over line conductor 1on the right of the consprings 8, impulse springs 7 of the calling deivice CD,transmitter 9, primary winding of induction coil 22to lineconductor 2, and thence to the exchange. As a result of the closure ofthis circuit the calling line conductors 1 and'2'are extended to theline relay of an idle selector or connector switch, depending upon thecapacity of the 1 system. The removal of the receiver also closes thereceiver circuit, which is a local circuit including the switch hook 21, the receiver 20, transmitter 9,'impulse springs 7, springs 8, thewinding 24 of the polarized relay, the condenser 6, and the secondarywinding of the induction coil 22.

Although the winding 24 of the polarized magnet is'included in theabove-described circuits, this magnet is not energized at this time dueto the normal current flow being in the wrong direction.

' The calling subscriber may now proceed to manipulate the dial of hiscalling device CD in accordance with the digits of the number "of thesubstation desired, whereby the automatic switches used in extending theconnection are operated in any well known man-' ner to complete thedesired connection. During the operation of the calling device theshuntsprings '10 are closed to short circuit the receiver andtransmitter. This is the usual provision made to reduce the resistanceandimpedance of the line circuit during the transmission of impulses,and to preventnoises in the receiver during the dialling operation. 4

' When the called subscriber responds to the thelsreceiver 20. Theshortcircuiting of the call, thevback-bridgerelay of the connectorusedin seizing the called line responds and reverses the line conductors1 and 12 as regards their battery connections. Current now flows overthexline circuit :and: through the winding 24 0i the polarizedmalgnetinthe rent in winding 24 of vthe polarized magnet 1 causes it "torotate its armature 'in a clockwise direction, that is, toward the coreof: coil 24. When the armature is attracted in this direction it carriesthe arm 13 to therig-ht,

permitting the springs 14, 15, and 16 to come into engagement. Thearmature itself,

16'short circuits the transmitter 9, and connectsthe resistance 17 in ashunt circuit across transmitter makes 1 it impossible for the callingsubscriber to talk to the called subscriber through the medium thereof,whilethe resist- -ance 17 prevents 'thesubscriber using the re- :ceiveras a transmitter, but does notprevent '1 the callinghubscriber fromhearing the to again separate. "place a direct short circuit around theWindcalled subscriber answer. p U When the calling "subscriber hears the-called subscriber answer, he depositsa coin in the coin chute. TheWeightof the coin strikinglever 3O causes thislever to release the' arm27 of lever 26, which, under thetension ofspring 32 now closes springs29 and raises arm 13 abovethe top of the tension spring 33, therebyallowingsprings 14:,1'5 and 16 Springs 29 in closing ing 245 so as toexclude it from the talking circuit. The separatingof the 'sprifngs,.14,

is-and 16 leaves the talking circuit for the calling substationinnorrnal condition, and

the two subscribers ihay converse oven the circuit s represented bytheheavily drawn lines.

After the conversation is completed, the.

calling and called subscribers replace their receivers.

It will be recalled that'when the called subscriber responded theoperation of armature 11 of the polarized relay resulted inthe" 610-coins as sure of springs 19. The closure of these springs completed acircuit extending from "line conductor 1 at the of condenser 6,throughsprings 19, winding 25 of thefpolarized magnet, theimpulsesprings transductioncoi122 tothe line conductor 2. This circuitis for restoring the paystation appara- ,tus, to normal, and it is noteffective ,while p the receiver is oil the hook at thestaticnjAraswinding 25 is short circuited by a cit-cut extending from the lowerterminal of winding 25, through thespringslQ- and: 29, and the closedswitch hook springs 8, back to the upper terminal of winding .25. i v aWhen the calling subscriber. replaces his receiver, this short circuitis removed at switchhook springs =8, leaving the winding 25 in bridge ofthe line conductors l and 2. reversed direction. This'reversal oftheicur- If the called subscriber has not as yetreplaced his receiver,upon the switchehook, nothing further happens at the exchange, as

"the current flow is still in the direction appropriate for rotatingarmature 11 clockwise. However, as soon as the called subscribersreceiver is replaced upon theswitch hook the direction of currentflowover conductors l 311(12 and through the winding 25 is restored'movement oflever 26 to its initial position permits lever 30 to restoreby gravity to its initial position, to again lock, the lever 26independent of thearmature 11 and to permit the lever 13 to again dropback of the tension spring 33. The openingof springs 19 interrupts thebridge formerly extended across line conductors 1 and 2-and includingthe winding 25, permitting the central ex 1 change apparatus to restoretonormal in the usual and well known manner. 1 Vwien the subscriber atsubstation A desires to make a toll call the connection is set up in thesome manner as for alocal call, butthe switches which extend aconnection to an operatordo not reverse the direction of current flow tothe calling line, consequently the polarized apparatus is not operatedand the calling subscriber is therefore not required .to 1 deposit acoin to converse with the toll operator.

Since the paystation device is equipped with openings for receivingdifierent sized coins and with signalling devicesfactuated bythe depositof coins, the toll operator at any time she desires may request that thecalling subscriber deposit the appropriate cointo pay forthe connection,the operator being informed of "the amount deposited by theusuallaudible signals produced by the they passonidown into the collectionboxr" i 1 What is claimed is: i
